This invention relates to locomotive tenders of the class equipped withStoker mechanism. The primary object is the provision of an unusuallylong tender of the character described.

In past practice, most of the tenders for Stoker fired locomotives wereprovided with a cast steel screw conveyor mounted in an open mouthtrough for advancing the fuel from the bunker to a conveyorrleadingforwardly from the tender to the locomotive. The length of the castscrew permissible with satisfactory operation is an Yirnportant factorin the design of tenders, particularly so on those transportationsystems where the trend of the design is toward the adoption of longertenders with greater fuel carrying capacity than those now in service.One design considered contemplates the use of a stoker conveyorapproximately 25 long which is about double the length of the conveyorsof past use. Many problems apparent to those skilled in the art arise inconnection with the use of such a conveyor.

This invention seeks to meet the problems by the provision in alocomotive tender of a stoker conveyor comprising a plurality ofsections disposed under the fuel bunker and arranged with the deliveryend of one of the sections being positioned above the receiving end ofanother. In one embodiment of the invention, as will presently appear,the stoker conveyor of the aforesaid construction is adapted for usewith a fuel bunker having a plurality of discharge outlets disposed indiiferent elevations.

Many specific objects and advantages of the invention will be apparentfrom the following description when read with the accompanying drawings,in which,

Fig. 1 is a vertical longitudinal central sectional view of thelocomotive tender of the invention;

Fig. 2 is an enlarged vertical transverse section taken on line 2 2 ofFig. 1;

Fig. 3 is an enlarged vertical transverse sectional view taken on theirregular line 3 3 of Fig. 1;

Fig. 4 is a view similar to Fig. 1 representing a modied form of theinvention;

Fig. 5 is a vertical transverse section taken on the irregular line 5 5of Fig. 4; and

Figs. 6, '7, 8 and 9 are enlarged vertical transverse sectional viewstaken on lines 6 6, 1 1, 3 8 and 9 2, respectively, of Fig. 4.

On the drawings, Figures 1 to 3 inclusive, illustrate the inventionembodied with a tender of the type wherein a separate compartment underthe bunker is provided to receive the stoker conveyor. For purposes ofdescription, this construction will be referred to as the preferredembodiment of the invention, although the structure illustrated inFigures 4 to 9 inclusive, may be preferred in service because additionalwater space is provided by placing the stoker conveyor as shown withinthe water compartment.

Referring to Figures l to 3, the improved tender as a whole isrepresented at A. It includes the underframe I above which is formed thewater compartment I I and the fuel bunker I2 separated by the rear andside partition plates as at I3 and I4 respectively. Extensions I3a andla of the rear and side partition plates form with the imperforate wallI of the underframe, a Stoker conveyor compartment I B. This compartmentis separated from the fuel bunker by the horizontally disposed oor I 'lconsisting of rearward and forward sections I'Ia and Ilb respectively,which are arranged in different elevations. Preferably, the rearwardfloor section is positioned in a horizontal plane above the forwardfloor section. Their adjacent ends are connected by an upstanding wallIB extending transversely thereof. Suitable brackets as at I9 andsupport the floor sections from the partition walls Ida.

The floor sections are centrally apertured at 2| and 22 respectively.The two constitute a downwardly opening discharge outlet in the bottomof the bunker. From another aspect of the invention, the apertures 2Iand 22 may be considered as fuel bunker discharge outlets disposed indifferent elevations. Discharge of fuel through the apertures or bunkeroutlets, is controlled by slidable plates 23 which are well known inpractice, but which never before have been disposed in series arrangedin different elevations. The slidable plates of the forward floorsection Ilb are carried in the seat 24 formed by any suitableconstruction of plates or bars on the underside of the floor; andsimilarly, the slidable plates of the rearward floor section are carriedin the seat 24a. The plates are pulled forward one at a time to providewhat may be called a shiftable opening as at 22 in Figure 1. As the fuelrecedes in the bunker the rearward plates are pulled forward insuccession.

It will be observed that the forward slide plate 23a of the rearwardfloor section I'Ia when pulled forward hangs over the wall I8 and restsin an inclined position upon the rearmost plate of the forward oorsection. A lug 25 depending from the forward slide plate 23a engages thewall I8 and restrains further continued forward movement of the plateand its acts also to maintain the plate in the inclined position asshown conventionally in Figure 1.

Fuel passing through the bunker discharge outlet is received by astolzer conveyor indicated as a whole by the letter S` This conveyor ismounted in a fixed position on the underframe EEB beneath the fuelbunker I2 in the conveyor compartment I6. It may be formed of anydesired number of i.

oifset sections, but preferably, it comprises the rearward section 25and the forward section 21".

These sections are made in tne form-of4 troughs, as best shown inFigures 2 and 3, and Yare disposed with the delivery end portion 26a-ofthe rearward trough section positioned above the receiving end portion21d of the forward trough section; The trough sections are showndisposed in horizontal planes one higher than the other, but it will. berecognized the one or both of them may be `placed in an inclinedposition vif desired.

Preferably,l the rear trough section 2B is mounted closely adjacent anddirectly beneath the bunker iioor section Ila', vand similarly,` theforward trough section 21' is disposed under the forward floor section'i 1b; 1 TheV adjacent ends of the trough sections are offset frornrone'another and the rearward troughsection is-'provided with the downwardlyopening passage- '2d-'communicating with the.receiving portion 27a ofthe forward trough section at 'a pointrearward of or directlyy adjacenttothefwall -I8 between thebunker iioor sections;

In this embodiment-of the invention the trough f-Isectionsare'-constructed-as separate units with thesectionvZT carriedbythe underframei@ and thesection A26secured in an elevated position to thefloor-section` Ha. Any suitable fastening membersmay be employed Vforholding the sections in their respective positions. Each unit or troughsection'containsa -screwasat Q9 and-3%, which l"screws serve to ladvancefthe=fuelthrough the stokerconveyor-to 4a Itransferl conveyor 3l leadingforwardly from theftender.- The rearward end ofthetransfer conveyor 3|.is `universally connected at 3la to theforward end of the deliver-y orforward trough "section V2li mounted over the forward end portion of thescrewlloooperates witlrthe-screwto break down lumps of` fuel too largeforfiring. Thesorews 2Q,

30' are of substantially the same length 'which is notl inexcessofthatdetermined-by practice to operate satisfactorily without bendingor-break ingand such that requires no bearings intermediateI the 'endsof thescrew;l In -longertenders more thanytwo separate screws maybefound necessary.v Thel use'ofv the separated screws is made possiblebytheprovision of the trough 'sections disposed in'different elevations.y

Suitablefmeans is provided for driving the-screws 29."and- SQ'from'their rearward ends. Forl this purpose'a gear drive is mounted-.at therearward end of each-trough sect-ion in housingsiand'.v

The screw- 30is connected-- to vthe -shaft- 353 which carries a gearyr-fmeshing withthe pinion {il} on thepinion-shaft 35i'. This shaft isconnectedto Va power, shaftl 39* extending forwardly to a primemover,not "shown:A The gear shaft 35 extends rearwardly from the housing3d and isuniversally rconnected-to the drive-shaft 5mi-which at itsrearwardlendis universally connected to la gear shaft'l-y Thisshaftcarries a Agear 52. .meshing within the housing 33 with a similar gear43 fixed on the-shaft'A 44- which lis operatively connected .to theVrearward end-of the screw'f-ZQG Hence, mo-

K trough sections 50 `and 5 l.

tion imparted by the power shaft 3S will be transmitted through the geardrives to the screws.

The forms of the invention described above is particularly applicablewhere it is desired or necessary to form the Stoker conveyor inseparable sections disposed in the customary conveyor com# partment. Theuse of this construction is made possible by forming the tender withthelfloor sections disposed in different elevations as heretoforedescribed. Figures 4 to 9 inclusive, illustrate a modification of theinvention now to be described. It employs the important feature of thepreferred form of the invention, in that the Stoker conveyor, mountedbeneath Vthelounker, is composed of sections disposed in differentelevations and offset at their adjacent ends. In this modied form theconveyor sections are formed as an integral structure mounted beneaththe fuel bunker in the water compartment of the tender. By reason offorming the sectionsras an integral unit-andplaoing the unit in thewaterlcompartment, a compact structure is provided such that in lmanyinstances` it will not be necessary to vconstruct the floor of thebunkenof sections disposed in different elevations asfin the preferredform of the invention.-

Referring to the aforesaid figures, the improved` tender -is representedasia whole at B. Above thel waterbottom underframe't, the fuel bunker 45f '30 by'side .partition plates l; and the rear plate 4E,- secured attheir lower marginal edges in any suitand the water compartment '36a.are separated ableimanner to thestoker `conveyor Vindicated generallyat 49. Theconveyor is an integral unit mounted-lin the water.compartment to contact the water therein and. arranged .to `provide forpassage `of water from one side of the tender to the other. Itmaybe/cast integral with `the uncast unit mountedon. the frame. endof theconveyor unit lis formed in any de.- sired manner with the front wall ofthe tender to1form a closure forthe water compartment.

Likein the preferred form of theinvention, the

stoken l.conveyor is composed of a plurality of secl v derframebutpreferably, it is built as a separate Y The forward..r

tions; The rearwardgsection 53; ispositioned in a Y horizontalrplane ina level above thereceiving end. of theV forward .sectiong l; whichis/inclined forwardly from a point below the delivery end `of the.

rearward section. A wall 52 unites the adjacent ends of therearward andforward sections. Eachy section isfmade in the form of a troughopeningupwardly to communicatev with the fuelY bunker. Discharge of fuel fromthe bunker -in to either trough section is controlled by a series ofslidable plates 53 positioned horizontally `inthe seat 5;

formed along the upper marginaledges of the,

VerallyYeXtending ledges 5E which in effect f orm a floor for the fuelbunker which iioor is apertured as at 5T. 'immediately above the troughforma- Y tions of the conveyorunit.

The conveyorscrews 58, and 59 of substantially theV same length aremounted respectively in the The forward end of screw 58. extends overand above the 'rearward end of the., screw 59 vwhereby the ,fuelconveyed along. thelrearwardtrough section ffwill be dischargeddownwardly in-to the receiving end portion; of @the forward. troughsectionl; on ,to the CTI screw 59 which advances the same forwardlybeyond the crusher 60 to any suitable mechanism for transferring thefuel from the tender to the locomotive, not shown.

'I'he screws 58 and 59 are driven from their rearward ends by gearingdisposed in a water tight housing 6| formed at the rearward end of thestoker conveyor 49 and extending downwardly through the underframe 45. Abracket structure indicated as a whole at 52 mounted underneath theunderframe and extending to one side thereof forms a laterally extendingcontinuation of the housing 6I and opening through a side of the tender.The bracket structure carries the prime mover or stoker drive engine B3.An endless chain 64 imparts motion from the prime mover to a sprocket 56on the pinion shaft 51. This shaft carries a pinion 68 in mesh with thedrive gear B9 on the shaft 'Hl which is operatively connected to therearward end of the screw 53. Another` pinion l! is also carried by thepinion shaft 51, which last named pinion engages the gear 'l2 fixed onthe drive shaft 73 which extends forwardly to a point within the forwardtrough section 5l where it is connected by a universal joint 'M to therearward end of the screw 59. The aforesaid gears and pinions arejournalled in a box 'l5 which is mounted on the rear transverse wall 'I6of the stoker conveyor unit 49 in a manner to form a water tight sleevetherewith. A bearing 'I1 carried by the wall 52 supports the forward endof the drive shaft 13. This shaft is protected from the water of thewater compartment by the sleeve 18 which surrounds the shaft and extendsbetween the wall 52 and the rear wall 16.

From the foregoing description it will be recognized that the screws 58and 59 are driven from their rearward ends by the primemover and thegear drive both of which are mounted in the water tight Yhousing 6I atthe rear of the conveyor unit.

In order to deliver the fuel at a point forward of the joint 'lll in theforward trough section 5i a removable iioor member 80 is pro-vided as anoverhanging extension of the rearward trough section 55. This floormember may be held in position by welding or any other suitable means.

'While the two trough sections are shown as formed in an integral unit,it will be understood that they may be formed separately as in thepreferred form of the invention or in any other desired manner such thatwill serve to arrange the sections whereby the delivery end of therearward trough section is disposed above the receiving end of theforward trough section at a point beneath the fuel bunker. Various otherchanges and modifications of the invention may be made without departingfrom the scope of the appended claims.
